Variety of rose plant named ‘Pejamblu’

ABSTRACT

A new and distinct cultivar of Rose plant named ‘Pejamblu’ is characterized in compact upright bush having a mauve/lilac color flowers ageing to a slate blue and having a strong pleasant fragrance. The plant also benefits from a lengthy flowering period of repeated flowerings between spring and fall. The plant is tolerant of dry conditions and exhibits tolerance to Black Spot and Powdery mildew, Rust mildew, and Downey mildew.

BACKGROUND OF THE NEW PLANT

The present invention relates to a new and distinct cultivar of Rose,species Rosa, and further known by the varietal name ‘Pejamblu.’ Thisnew variety is also sold under the Breeder's reference name PEJAMBLU.The new variety was discovered through selective cross-pollinationinitiated in June 2000. The seed parent is known as “Rose ‘NATURALBEAUTY’ (ROGSCRIV)”, a pink/apricot colored rose having double 26-40petals of a 75 mm rosette borne on small clusters. No patent is known bythe inventor to cover the parental seed. The pollen parent seedling wasderived from a cross of SUMMER WINE and SCRIVBELL. PEJAMBLU has a uniquemauve/lilac flower ageing to slate blue, with semi-double 12-16 petalsand 75-100 mm flowers. The derivation by cross pollination occurred at324 City Road, Tividale, Oldbury, West Midlands, United Kingdom B691QP.The first asexual reproduction occurred at the breeder Peter James' homeat 324 City Road, Tividale B691QP, Oldbury West Midlands, U.K. Plantswere budded on to Lasca under stock and proved to be true to type whengrown over several generations and all have been stable. Propagation bycuttings in Australia has also proved stable, and the desirable featuresof the plant have remained constant throughout the evaluation period.The evaluation of the variety was carried out at Warner Roses ofShropshire. U.K. TF109EP.

SUMMARY OF THE INVENTION

Plants of the new Rose variety can be compared to other plants of itsgenus. ‘Pejamblu’ is characterized by its coloring, its abundant darkgreen foliage, its strong pleasant fragrance, and its abundant flowers.The variety is distinct in its flower color, mauve fading to slate blue,appearing very blue under normal climatic conditions. The variety has avery strong sweet citrus fragrance, and the foliage is plentiful andsemi-malt in appearance. The habit of ‘Pejamblu’ is medium height andcompact bushing as opposed to spreading, and it possesses a largerflower size and multiple flowerings between Spring and Fall.
